Here's an up to date FTS. I will use this shot for comparison, it was simply shot with the WB set to the sand, cropped in PS and that's it.
The current light fixture is a 4 bulb T5 fixture, nothing special, got it used for $100 including bulbs. It really does seem to be enough light for the tank although I don't have any SPS at the moment I still think a few would survive in the right spots.
Although the LED fixture will have more light it has so far cost me just under $1200, and that's without any labor which is proving to be a lot.
